The Lincoln Navigator commercials that I've seen hav used the song 'Get A Move On' by Mr. Scruff. Here's a link to a page that has samples of the song (Real Player format) to be sure this is the one you're looking for.http://www.amazon.com/exec/obidos/tg/detail/-/B00000J5XW/ref%3Dnosim/musicfromtvcomme/104-0794543-5865509
